Abstract

This paper proposed an eccentric annular ring microstrip antenna which has an asymmetric slot and a tuning stub for improving bandwidth and size of the circular microstrip patch antenna. The field characteristics of the eccentric annular ring microstrip antenna have been calculated by using the method of FDTD (finite difference time domain). The calculated results showed good agreement with the measured results. As a result of measurement, the antenna size and the bandwidth has been improved to that of 12.2 % and 4.8 % respectively, comparing to circular microstrip patch antenna.

본 논문에서는 원형 패치 내부에 비 동심으로 원형 슬롯을 내고, 동조 스터브를 두어 원형 패치 안테나의 크기와 협대역 특성이 개선되는 비 동심 링 안테나를 제안하였다. 비 동심 링 구조 마이크로스트립 안테나는 FDTD 방법을 이용하여 해석하였고, 해석치는 측정치와 잘 일치함을 알 수 있었다. 측정 결과 원형 패치 안테나와 비교하여 안테나의 크기는 12.2%, 대역폭은 4.8% 향상되었다.
